Image Processing Adjustments

Just like the recently reviewed Coolpix 4500 the 5700 provides
control over three different parameters associated with the cameras internal
'post-shot' image processing algorithms. However unlike the 4500 the parameters
associated with each setting are closer to the 5000. These are Tone (labelled
'Image Adjustment'), Saturation (Colour) and Sharpening. Each of these
three parameters can be set independently to best suit your preferred
'look' or the type of shot.

Image Adjustment (Tone)

Auto

Normal

More Contrast

Less Contrast

Lighten Image

Darken Image

In this example the Auto setting seemed to choose the Normal tone curve,
as we'd expect 'More Contrast' does just that and produces a much punchier
higher contrast image. As we've seen on other Coolpix digital cameras
is the appearance of a 'Less Contrast' image which not seems to not only
reduce the image contrast but also its brightness. In my opinion 'Image
Adjustment' should be renamed to 'Tone' or 'Contrast' and the 'Less Contrast'
option should be re-labelled.

Saturation Control (Color)

On the 5700 you have one positive and two negative levels of color saturation
adjustment above and below 'Normal'.

Maximum (+1)

Normal (0)

Moderate (-1)

Minimum (-2)

Black & White

Sharpening

The Coolpix 5700 provides four selectable sharpening levels as well as
the 'Auto' setting which will analyse image detail and automatically choose
the most appropriate level of sharpening.

Auto

High

Normal

Low

Off

'Clear Image Mode' Noise Reduction

We first saw the 'Clear Image Mode' option (SXGA or lower
only) on the Coolpix 5000, it's intended to "Minimizes noise and
improves color gradation in SXGA or smaller size images." (from the
5700 manual). In this mode the camera takes three exposures, two with
the shutter open and one with it closed. It uses these three images to
compare noise and produce the final image. What I've never understood
is that this option doesn't appear to improve anything and only serves
to destroy vertical resolution. Very strange.
